Especifica\u00e7\u00f5es t\u00e9cnicas<\/h2>\n

O ECM-B9745AL30RC-IP67 \u00e9 uma c\u00e1psula de microfone omnidirecional de 9,7 \u00d7 4,5 mm equipada com uma malha \u00e0 prova d'\u00e1gua com classifica\u00e7\u00e3o IP67. Projetada para uso em ambientes agressivos ou \u00famidos, essa c\u00e1psula garante uma captura de \u00e1udio confi\u00e1vel com prote\u00e7\u00e3o contra poeira e entrada de \u00e1gua.<\/p>\n

Sua sensibilidade de -30 dB, a ampla resposta de frequ\u00eancia de 20 Hz a 16 KHz e a alta rela\u00e7\u00e3o sinal\/ru\u00eddo de 74 dB permitem a captura precisa do som a longa dist\u00e2ncia. O n\u00facleo do microfone de RF coreano garante um desempenho de \u00e1udio est\u00e1vel e consistente, tornando-o ideal para dispositivos de capta\u00e7\u00e3o remota \u00e0 prova d'\u00e1gua e microfones robustos.<\/p>\n
